    Enclosure Design for 12" Alpine Type E (SWE-1243)

    Vehicle : 1987 Shelby GLHS - small 2 door hatchback
    Location in the vehicle: In the hatch/trunk area
    Space available (Length x Width x Height): Plenty
    Subwoofer make and model: Alpine SWE-1243
    Subwoofer Size: 12"
    Number of Subwoofers: 1
    Type of Port (Kerfed, Slot, Aero, etc.): ???
    What type of music do you like?: Dubstep, House, Rap
    Is your goal SPL or Everyday Music?: Everyday Driver
    Tuning Freq (Hz): ???
    Volume : ???
    Questions:

    Im a complete noob to car audio, looking to put my first system together. Picked up a new in box Alpine SWE-1243 subwoofer off of craigslist for a good deal and am having trouble designing an enclosure as I have no idea what is optimal for this subwoofer.

    The subwoofer will be placed in the rear of the vehicle and powered by a PPI PC250 amp, giving it an underrated 200 watts RMS.

    I am open to either a sealed or ported enclosure as I'm not sure what is better for the subwoofer and the kind of music I like to listen to.

    When I tried modeling the subwoofer in a few online calculators they always came back recommending like 8 cubic feet for a sealed enclosure or something ridiculous as optimal, soo I'm pretty sure I was doing something wrong.

    Anyway, I could really appreciate some advice on what to do with this sub!

    Thanks,
    James

    It was listed in the post, should probably highlight it lol.. "PPI PC250 amp, giving it an underrated 200 watts RMS"

    I'm actually from SRQ, go to school in Orlando. Looking to build it myself, just not sure where to start!

    Thanks for the help! Just wondering, where did you find what was recommended by the manufacturer? Also what are the specs on the box you linked me too?

    In the manual it recommends this:



    Its the specs on the right hand column for the 12"

    Youre talking about the 1.6 cubes tuned to 32Hz right? Originally when I clicked the link it sent me to one for 2 cubes at 34Hz
